IMPROVEMENTDIN MACHINES FOR MAKING PAPER BOXES.

Specification forming part of lLetters Patent No. S5, 301, datedDecember 29, 1868.

To allV whom t may concern:

Be it known that we, WILLIAM GATES and DAVID J L LLOYD, both ofFrankfort, ,in 'the county of Herkimer and State of -New York, andASAMUEL MILLER, of South Hammond, in the county of yJefferson and Stateof New York, havel invented 'a new and Improved Machine for MakingPaperBoxes 5 and we dohereby declare that the following is a full, clear, andexact description thereof, which will enable those skilled in the art tomake and use the same, reference being hadl to the 'accompanyingdrawings, forming part of this specifica tion'.

This invention relates to a new and im# proved machine for making paperboxes, such as are "of square'or,rectangularvforinin their transversesection, and is an improvement on a machine for` the same purposepatented by R. L. Hawes, April 24, 1855; and the: object of the presentinvention is to vobviate several difficulties attending theoperation ofthe orig- 'inal machine, a practical use of which forY a number-.ofyears having suggested 'a number of improvements, all of which arehereinafter fully shown and described. i o In the accompanying sheet ofdrawings, Figurel, Sheet No. 1, is a side elevation of our invention;Fig. 2, an end elevation of the same; Fig". 3, Sheet, No. 2, fa sidesectional view of the same, taken in the line wx, Fig. 4 5 Fig. 4, atransverse section of the same, taken inthe liney y, Fig. 3; 'Fig'.,Sheet No. 3, a section of a portion ofthe same, taken in the line z z,Fig. 4; Fig. 6, a detached perspective view of certain. parts pertainingto the same; Fig; 7, 'a detached face view of acutter perf taining tothe same; Fig. 8,' a section of ay paste-box pertaining to the same,taken in the line zf jz, Fig'. 3; Fig. 9, an enlarged face view of aportion of the paper strip from which the boxes are made, showing howthe paste is apf plied; Fig. l0, an enlarged face view of a portion ofthe same, cut oft' the required length to form abox Fig. 11, a' detachedenlarged perl spective view of a paper box.

- A Arepresents the frame ofthe machine, which may be constructed vinany proper manner Vto vsupport the workin g parts, and B represents'rests upon an elevated portion of the frame A, and in which box thereare lsecuredftwo standards, a', tov serve as ,bearingsvv for the kshaftsb b", placed one above the other in the same axial plane, and havingrollers x on their inner ends, said rollers beingin 'contact with eachother when the paper of which the boxes are made is not passing betweenthem. o The lower roller DX of the lower shaft. b is made of wood orother suitable material, which is somewhat absorbent, and this rollerl)X works in and is kept moist by the water in theubox O, and meistens oneedge of the strip o f paper as it passes into the machine, said edgebeing designated Vby c in Figs.- 9 Vand 10,'Sheet No. 3.

The paper strip, being designated by E, and,

.'besides, bein g shown separatelyV in Figs. 9 and l0, is shown in itspassage from a continuous 'roll Ainto or through the Amachine in Figsland 3. This portion" or edge o ofthel paper strip which isthusgmoistened; is" thepart lof which the bottoms of theboxes are made,and

the object oimoistening it is to facilitate the folding and insure `thatportion vof the work being performed ina smooth and neat man- Frepresents a fountain, which is" attached to or rests upon an arm, d,attachedA toy the upper part of the back B. This fountain is elevatedabove all the working parts ,of the machine, and it supplies,.by meansofthe tubes e o, flexible or otherwise, paste or muoilageto the twopaste-boxes G GX?. Y This fountain'may be made of quite large capacity,much larger than the two `paste-boxes combined, asgthe former may besufficiently elevated 'astobe entirely out of the way, and made ofanyconvenient size, whereas thel capacity vofthe paste-boxes isrestricted, owing to theirnecessary closer proximity to theworkingApartsbf the machine.. n f i f i By this arrangement, therefore,thepastea boxes may be'kept supplied a longgtimewith paste or mucilage, andthe trouble and inconvenience of frequently replenishing the pasteAboxesavoided. l v

'The paste-boxes G GX are placed on the inner end of a lever, B',connected with it, said levers bein g pivoted to the inner side of theplate S, and each having a spiral spring, u, attached to it, whichsprings have a tendency to keep the jaws q off from the plungers L whenthe machine is at work, and which effect this end after fiat springs cat the outer ends of the levers B' pass the plate A', said plate A',when adjusted so as to .project over or beyondthe edge of the back B,being in the path of the rotation of the levers B' and springs fu, andthe latter Ab eing of sucha length that they will be forced .backward inAorder to pass underneath plate A', and vth ereby actuate the levers'B,so as to cause the jaws q to project over the plungers L.

By adjusting the plate A' backward, so that it will not p rojectbeyond,the edge of the back B, and be koutof the path of the rotation of thesprings u of the levers B', the jawsql will be rendered inoperative. Bythis simple adjustment ofthe plateiA" the platens Ware preservedfrominjurygwhen theshaft Nand plates M S are 'rotated for the purpose ofremoving the plungers from the machine.I

Hitherto the platens W/were very frequently injured .by the jaws gcoming in contact with them after the plunger above ithad been removed,no means having beendevised in the originalmachine to render the jawsinopera- .tive when -the machine was not at workand the driving-shaftturned in order to vremove the plungers for the purpose of cleaning,repairing, Stc. j g

The plungersL having been described as having an inward movement y attheir rear ends caused by thestationaryhor flxedcam B, Fig. 5, lit isnecessary to limit thisinward movement; and this part of `the inventionrefers to means to effect that endwhich consist of stops w, (see Fig.4,) which are .simply setscrews inserted in a hub, a', projectingradially from the inner side of the plate l 0'0" 0'." 0"" representfolders which operate against the bottoms `of the boxes, folding thepaper s o as to form the boxes.. The folders 0' are pivoted in or to aspur-wheel, D', `on the driving-shaft N, the'outer ends of saidfoldersthaving each e a spiral spring, b', attached, which springs ,havea tendencyto keep thefolders 0' y in-contac'tlwith the inner side ofthewheel D', (see Fig.. 4,) said folders being forced out from the wheel D'asv1 they come in contact with'a xture, c', vattached to ther frame ofthe machine. (See FigA.)

There is onlyone folder 0", and this is at thelower end of a lever, E',which is attached to vthe frame, .and is operated by a spiral spring,d', and projecting pins e' at the outer side of the wheel D'. (SeeFig.'2.)

There is also but one folder 0'", and this projects from a tube, j",Figs. 3, 2, and 1, on a shaft in the upper part of the framing, saidtube f' having an arm, g', extending from it,

with a roller, h', at its outer end, said roller being made to bear onthe periphery of the plate S, which performs the oice of a cam by onthesameshaft'as the tube f',`to which the folder 0"' vis attached, saidfolder 0"" being in line with or directlyover the-platens W. This folderis raised by an arm, b", having a roller, of, on its ends, which is madeto bear upon the periphery of S bymeans of a spiral Spring, dxv F, Figs.3 and 7', represents abox or case, which is attached to a shaft, 9*, inthe framing, and has within it a guard, 0r, Figs. 3 and 7, upon which aspring, H', bears. At the rear of this guardGr' a knife', or cutter, I,is placed, which is Vsecured .in position by av plate, I', andset-screws h'. This guard holds the paper down while being c ut betweenthe cutter I and a cutter, i", which is fsecured by screwsjx to eachwall or surface p, the

cutter I having a slight movement whileeff ecting its c ut, inconsequenceof. aspiral spring, kf, which is connected to'an upright arm,l', on shaft g", Fig. l, throwing back the cutter after beingraised bythe pins e', 2,' of wheel D' coming in contact with an arm, J x, Fig. 1,which extends f'rornthe shaft g'x. The folding-jaws g, Fig. 6, havetheir pivots von shafts mx, the lowcrends of the jaws resting onbearings n' on the shaft, and having guide-pins 0"'passingvv throughthem, and the lower ends of the jaws have aspring, 10'., restingl onthem. j

The object of these springs is to admit of the folding-jaws rising Atoaccommodate them-- selves to the different thicknesses of paper beingfolded over the plungers, and in case two thicknesses of paper shouldaccidentally pass into the machine.l

K' represents a inishing-roller, which works overthe lapped edges of:the folded paper on the outer side of the plungers as the latter aremoved out from the platens or tables W. This roller 4is fittedbetweentwo spring or elastic arm's,.q' q',','( see Fig..2,) vwhich extend froma shaft, L', in the framing, saidshaft havinglan arm, y', projectingfrom one end of it, which has a bent lever, M', in contact with it, andthis leverA is actuated at the proper time by the pins e' of the, wheelD', soas to throw vthe roller K' in cojntactwith thelapped surface ofthe. paper on the plungers, the roller smoothingsaid surfaces' ,ai1dgiving them a finished appearance. Y rvv 'Ihesprings .or elastic arms q'q' admitr of the roller yielding or giving to anyirregularity of surfaceover which it may pass. e

'N' represents a slide, which is fitted on `a vertical guide, O', in theframing, and is .a1- lowed .to work freely up and down thereon. Thisslide has two curved rods, s s', attached to its upper end, and an arm,t', is pivoted to it, which arm extends down and is pivoted at its lowerend tol one end of a lever, P', the outer end of the latter beingpivoted to an upright rod, Q', the upper end of which is pivoted to jawq.

:the'lo'wer of two parallel levers, R' It', (see Fig. 1,) said leversbeing pivoted at one' end to the framing of the machine, as shown at u',

and the opposite ends connected by a bar, 'u'.v

These levershave each an inclined projection,

w', attached to or fitted in. them in any suit; .able wayy against whichradial rods w', iitted in or attached to a hub, S', on the shaft N, act,said rods and projections, in` connection .with a. spring, y', connectedto lever P', the

levers It' R', and the means by which they are connected to the slide N'giving an up-and` down movement to the slide N', the curved rods s' s'on the top of which, as they descend, insuring the discharge of thenished boxes from the machine.

Having thus describedV the several parts -with more especial freferenceto those parts which are novel, and comprise the subject matter of `thisspecification. The endless roll of paper E passes between the rollers 'DD,

`which moisten the edge c, then passes over guide-rollers a* a.X anddown between the -rollers J J, where the moistened edge c is pasted, andstrips b", which extend transversely across the paper, (see Fig. 9,) thepasted strips b X being at equal distances apart.

-The paper is cut at one edge of each pasted strip b", (see Fig.10,)which shows the length required for the folding of a boX. The cutsare effected by the cutter I as each cutter i* V`-passes underneath it,the guard G' holding the paper while it is being cut, and preventing thepaper being folded back while being cut. The paper, during this cuttingprocess, is between the plungers L and the tables or platens W; and, tofacilitate the passage of the plun gers over the paper while the plungers are being moved forwardunder the action of the levers U and thefixed camsVV, the outer ends of the plungers are raised in consequenceof the rear ends of the same coming in coiitact with the xed cam It, aspreviously alluded to.

After each strip of paperis cut, the plunger directly over it is forceddown in consequence of its slide 'I being pressed down by its rollerrcoining in contact with the wide portion Y of the rim of the back B,the platen or table W underneath the plunger being, of course, presseddown. The foldingjaw .q Vis then moved in consequence of the spring 'v`of its lever B' coming in contact with the curved plate A', and thefolders G"" then fold down the pasted edge bx., which laps over theother edge folded down upon the plunger L by the The bottom of the box,Fig. 11, is folded by the folders C', which turn over one end, l, of

the jsame, the folder C", which turns over or back the other end, 2, thefolder 0"', which turns down the flap 3, and the folder C", which by oneupward movement turns up the flap 4. The lapped surfaces of the paperare then rolled by the rollerV K', which is moved off from the box atthe proper time, the plunger L previously moving outward toward theroller. The plunger L is then drawn baci: under the influence of itslever U, actuated by the cam V, and the descent of the slide N' with therods s' attached insures the dis charge of the finished box from themachine.

The operation of each of the plungers is precisely the same as the onedescribed.

We would remark that the covers `of the boxes are made in precisely'thesame way as the bodies or main portions, the difference between the twoconsisting only of dimensions.'

We claim as new and desire to secure by Letters Patentl.` rlhemoistening of one edge, c, of the continuous paper roll E by means of awooden anda metal roller, D Dx, applied to a pa per box, substantiallyas shown and described.
